In PL/SQL, the pragma EXCEPTION_INIT tells the compiler to associate an exception name with an Oracle error number. Make sure you pass negative error numbers to SQLERRM. Though they share the same name, the two past_due exceptions are different, just as the two acct_num variables share the same name but are different variables. But remember, an exception is an error condition, not a data item.

CASE 3: Then I reran everything, except the unnamed block had a generic when others then null; error trap, and the stored procedure had a generic when others the null; error Home Book List Contents Index Master Index Feedback current community chat Stack Overflow Meta Stack Overflow your communities Sign up or log in to customize your list. The technique is: Encase the transaction in a sub-block. Oracle Sqlcode List DUP_VAL_ON_INDEX 00001 -1 A program attempts to store duplicate values in a column that is constrained by a unique index.

You can avoid unhandled exceptions by coding an OTHERS handler at the topmost level of every PL/SQL program. Sqlerror Once the exception name is lost, only an OTHERS handler can catch the exception. For internal exceptions, SQLCODE returns the number of the Oracle error. https://docs.oracle.com/cd/B28359_01/appdev.111/b28370/sqlerrm_function.htm But, if the need arises, you can use a locator variable to track statement execution, as follows: DECLARE stmt INTEGER := 1; -- designates 1st SELECT statement BEGIN SELECT ...

For example, perhaps a table you query will have columns added or deleted, or their types changed. Sqlerrm Line Number Scope Rules for PL/SQL Exceptions You cannot declare an exception twice in the same block. When an error occurs, an exception is raised. To handle other Oracle errors, you can use the OTHERS handler.


Example 10-15 Controlling the Display of PL/SQL Warnings -- To focus on one aspect ALTER SESSION SET PLSQL_WARNINGS='ENABLE:PERFORMANCE'; -- Recompile with extra checking ALTER PROCEDURE loc_var COMPILE PLSQL_WARNINGS='ENABLE:PERFORMANCE' REUSE SETTINGS; -- http://stackoverflow.com/questions/12327643/how-to-catch-and-return-or-print-an-exception-in-an-oracle-pl-sql-create-or-re As the following example shows, use of the OTHERS handler guarantees that no exception will go unhandled: EXCEPTION WHEN ... Pl Sql Sqlcode This parameter can be set at the system level or the session level. Oracle Sql Codes List If so, do it by making a call to a procedure declared with the PRAGMA AUTONOMOUS_TRANSACTION, so that you can commit your debugging information, even if you roll back the work

Thus HandleAll should have been called with p_Top = TRUE. */ PROCEDURE StoreStacks(p_Module IN errors.module%TYPE, p_SeqNum OUT errors.seq_number%TYPE, p_CommitFlag BOOLEAN DEFAULT FALSE); END ErrorPkg; / Error Handling Package Body CREATE OR RAISE_APPLICATION_ERROR is part of package DBMS_STANDARD, and as with package STANDARD, you do not need to qualify references to it. You cannot use SQLERRM directly in a SQL statement. All Rights Reserved. Functions For Error Trapping Are Contained In Which Section Of A Pl/sql Block

PERFORMANCE: Messages for conditions that might cause performance problems, such as passing a VARCHAR2 value to a NUMBER column in an INSERT statement. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. How do you say "you all" in Esperanto? http://setiweb.org/pl-sql/pl-sql-exception-print-error-message.php Example 10-4 Using PRAGMA EXCEPTION_INIT DECLARE deadlock_detected EXCEPTION; PRAGMA EXCEPTION_INIT(deadlock_detected, -60); BEGIN NULL; -- Some operation that causes an ORA-00060 error EXCEPTION WHEN deadlock_detected THEN NULL; -- handle the error END;

If you redeclare a global exception in a sub-block, the local declaration prevails. Sqlerrm Invalid Identifier In other words, you cannot resume processing where you left off. END; Omitting the exception name in a RAISE statement--allowed only in an exception handler--reraises the current exception.

WHEN ZERO_DIVIDE THEN -- handles 'division by zero' error DBMS_OUTPUT.PUT_LINE('Company must have had zero earnings.'); pe_ratio := NULL; WHEN OTHERS THEN -- handles all other errors DBMS_OUTPUT.PUT_LINE('Some other kind of error

For example, in the Oracle Precompilers environment, any database changes made by a failed SQL statement or PL/SQL block are rolled back. That is, the exception reproduces itself in successive enclosing blocks until a handler is found or there are no more blocks to search. PL/SQL Warning Categories PL/SQL warning messages are divided into categories, so that you can suppress or display groups of similar warnings during compilation. Sqlerrcode USERENV_COMMITSCN_ERROR ORA-01725 Added for USERENV enhancement, bug 1622213.

You declare an exception by introducing its name, followed by the keyword EXCEPTION. In such cases, you must use dot notation to specify the predefined exception, as follows: EXCEPTION WHEN invalid_number OR STANDARD.INVALID_NUMBER THEN -- handle the error END; How PL/SQL Exceptions Are Raised Thus, the RAISE statement and the WHEN clause refer to different exceptions. Example 10-1 Runtime Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calculation might cause division-by-zero error.

Longest "De Bruijn phrase" in English How to add non-latin entries in hosts file Why do neural network researchers care about epochs? Errors are especially likely during arithmetic calculations, string manipulation, and database operations. So, an exception raised inside a handler propagates immediately to the enclosing block, which is searched to find a handler for the newly raised exception. Which one to use?

Every Oracle error has a number, but exceptions must be handled by name. For user-defined exceptions, SQLCODE returns +1 and SQLERRM returns the message User-Defined Exception unless you used the pragma EXCEPTION_INIT to associate the exception name with an Oracle error number, in which asked 5 years ago viewed 34307 times active 1 month ago Linked 1 Stored procedures with triggers oracle 11g 0 pl sql exception message 0 PL SQL handling exeception(get the query) Asking for a written form filled in ALL CAPS Find the super palindromes!

However, when an exception is raised inside a cursor FOR loop, the cursor is closed implicitly before the handler is invoked. LOGIN_DENIED ORA-01017 Invalid name and/or password for the instance. The maximum length string that SQLERRM will return is 512 characters. If you need to know which statement failed, you can use a locator variable: Example 10-14 Using a Locator Variable to Identify the Location of an Exception CREATE OR REPLACE PROCEDURE
